the former work, the essential features of any thorough system of house-drainage are laid down to be: Extension of all soil and waste pipes through and above the roof; provision of a fresh-air inlet in the drain at the foot of the soil and waste pipe systems; the trapping of the main drain outside of the fresh-air inlet, to exclude the sewer-gases from the house; provision of each fixture, as near as possible to it, with a suitable trap; and provision of vent-pipes to such traps under fixtures as are liable to be emptied by siphonage.

Leaving distilled liquors to take care of themselves, if they can, they contend that the beverages in which they are interested are wholesome, and are not instigators of crime, and that the use of them serves as a foil and a check to indulgence in stronger liquors; therefore it ought not to be discouraged.

present volume of Mr. Collins's "Mineralogy" is intended to accompany and supplement the first volume, which was published in 1878; and, like that, was written for the use of "practical working miners, quarrymen, and field geologists," as well as of students.
